US and Iran clinch tentative ceasefire deal, but Trump's signature remains uncertain

Iran Peace Deal Analysis for May 29, 2026

Negotiators have reached a tentative agreement on a 60-day ceasefire extension and nuclear talks framework, according to multiple U.S. and Iranian officials. The deal addresses the critical Strait of Hormuz reopening and includes provisions for both sides to reduce military posturing. However, the agreement hinges entirely on Trump's formal approval, which remains unclear. Vice President Vance stated the decision is "still TBD" as of Friday morning, and Trump himself has signaled reluctance to rush the process despite months of negotiations.

The past 48 hours reveal a sharp inflection point. After the ceasefire collapsed under mutual recriminations on May 28, both sides pivoted from blame to concrete negotiating. Negotiators produced draft text that satisfied enough core demands (particularly Iran's insistence on the Strait remaining open and U.S. demands for nuclear monitoring) to move toward finalization. Oil markets have begun repricing downward on ceasefire expectations, suggesting serious market players believe a deal framework exists. Yet the gap between technical agreement and political ratification remains the fundamental obstacle.

Watch whether Trump issues a statement within 48 hours endorsing the deal or requesting revisions. Israeli allies are being consulted on the draft, which could trigger new conditions or delays. If Iran or hardline factions within Tehran withdraw support during the approval window, the entire structure collapses. The next flash point is whether either side uses the waiting period to resume strikes, testing whether the ceasefire holds without Trump's formal sign-off.
